SpaceNav GPS Receiver for Space Applications

SpaceNav is a GPS receiver for satellite applications. It is a fully dual-redundant, radiation-tolerant, 12-channel L1 C/A code receiver. The system provides precise orbit determination and timing for low-earth-orbit satellites and host vehicles.

SpaceNav includes a special orbital filter algorithm that provides navigation-aiding data, smoothing the GPS navigation solution to provide the host spacecraft with more accurate guidance.

SpaceNav includes an error detection and correction mechanism that enables automatic detection and correction of single-event upsets, allowing this GPS receiver to continue functioning in space.
